Abstract
The invention provides a tunnel ventilation fan with an adjustable speed. The tunnel ventilation fan comprises a fan body, a timer, a controller, a fixing frame, a frequency converter and fixing holes. The fixing frame is installed on the upper portion of the fan body, the timer, the controller and the frequency converter are sequentially arranged on the fixing frame, the fixing holes are formed in two sides of the fixing frame, the timer is connected with the controller through a guide line, the controller is connected with the frequency converter through a guide line, and the frequency converter is connected with a motor inside the fan body through a guide line; the fixing frame is of a U shape; the controller is an AVR single chip microcomputer control system. Compared with the prior art, the tunnel ventilation fan is provided with the timer, the timer is intelligently controlled at midnight to enable the fan to operate at a low speed, energy is saved, and meanwhile the service life of the tunnel ventilation fan is longer.
Description
Technical field
The present invention relates to a kind of variable-speed tunnel fan, belong to the tunneling technique field.
Background technique
Along with scientific and technological progress, opened a large amount of tunnels between mountain, promoted the development of traffic, also driven expanding economy simultaneously, the circulation that blower fan promotes air generally all is installed in tunnel, at present the blower fan in tunnel is all generally to operate in 24 hours, has also just caused the waste of the energy operating at full capacity like this when midnight, wagon flow was few, is urgent problem.
Summary of the invention
The purpose of this invention is to provide a kind of variable-speed tunnel fan.
The problem to be solved in the present invention is the deficiency that the blower fan in existing tunnel is operated with full load in 24 hours.
A kind of variable-speed tunnel fan, comprise blower fan, timer, controller, fixing frame, frequency variator and fixed hole, described blower fan top is equipped with fixing frame, timer, controller and frequency variator are installed on fixing frame successively, the fixing frame both sides are provided with fixed hole, timer is connected with controller by wire, and controller is connected with frequency variator by wire, and frequency variator is connected with the motor in blower fan by wire.
Described fixing frame is U-shaped.
Described controller is the AVR single-chip computer control system.
Advantage of the present invention: compared with prior art, this blower fan is provided with timing device, when midnight, by intelligent control, makes blower fan carry out low cruise, energy saving, and longer service life, should have market prospects widely simultaneously.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of variable-speed tunnel fan of the present invention;
In figure: 1, blower fan 2, timer 3, controller 4, fixing frame 5, frequency variator 6, fixed hole.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
A kind of variable-speed tunnel fan, comprise blower fan 1, timer 2, controller 3, fixing frame 4, frequency variator 5 and fixed hole 6, described blower fan 1 top is equipped with fixing frame 4, timer 2, controller 3 and frequency variator 5 are installed on fixing frame 4 successively, fixing frame 4 both sides are provided with fixed hole 6, timer 2 is connected with controller 3 by wire, and controller 3 is connected with frequency variator 5 by wire, and frequency variator 5 is connected with the motor in blower fan 1 by wire.
Described fixing frame 4 is U-shaped, and structural strength is large, easy for installation.
Described controller 3 is the AVR single-chip computer control system, for to frequency variator 5, sending variable rate signal.
Using method of the present invention, this blower fan is arranged on to tunnel top by the fixed hole 6 on fixing frame 4, timer 2 sets timing, as sent a signal to controller 3 to 5:00 AM 12 of midnight, controller 3 is controlled 5 pairs of blower fans of frequency variator 1 and is carried out fall-back, good energy-conserving effect, simple to operation.
